Were you looking for information on Advair? Adevar is a common misspelling of Advair.
Advair® is a "controller medication" approved to prevent airway spasms due to asthma and to treat these spasms in people with chronic obstructive pulmonary disease (COPD). As a controller medication, it can prevent asthma attacks. However, Advair does not work quickly enough to treat asthma attacks once they occur. There are no universally accepted off-label Advair uses at this time.
